I will let her chill for a bit then try to talk her out from under the blanket. Actually she has a little spot where she can see me. but she is quiet.
Try ignoring her or just talk to her as you normally would but don't try to coax her from under the blanket. There is the possibility she uses her behavior to get special attention from you. Not sure which one of you would be the Pavlov dog in that situation. Maybe you're feeding off of each other. In any event, try not to coddle her these next couple of weeks and see what happens. She may get mad at you for not bowing to her every whisker twitch, but she'll get over it and adjust to the new paradigm.
